Abstract  Auto-calibration system of vector hydrophone has very important value in acoustic measurement. The system can accomplish low frequency auto-calibration of vector hydrophone. It can measure the signal amplitude of the standard hydrophone by dynamic signal acquisition. The sound field distribution is tested in the standing wave field. The standard uncertainty and expanded uncertainty of the system are analyzed and discussed. The comparison testing is given for pressure sensitivity. The expanded uncertainty of the system is 1.6dB.
